Answer 1

Answer:

129

Step-by-step explanation:

Use PEMDAS.

Parenthesis: (Multiply, then divide) 3*2=6,   12/6=2

Exponents:8^2=64

Multiply: 9*2=18

(No subtraction here!)

Add: 82+18

=129

(idk how, but i put it in the calc. and it came out as 129 soo...)

Answer 2

Answer:

129

Step-by-step explanation:

The order of operations is PEMDAS

P = parenthesis

E = exponents

M = multiplication

D = division

A = addition

s = subtraction

starting with

$8^{2}$ + 9 (12 / 3 x 2) - 7

We first work the terms in the parenthesis ( 12 / 3 x 2)

A rule is if all the operations are multiplication and division only we work from left to right so (4 x 2) then (8)

$8^{2}$ + 9(8) - 7

Next we take care of the exponent (the remaining parenthesis are a multiplication operation not parenthesis that contain other operations)

64 + 9(8) - 7

Next we do the multiplication

64 + 72 - 7

Another rule is if all the operations are addition and subtraction we work from left to right

136 - 7
